Description
The present invention relates to butene-1 copolymer composition, more specifically, the present invention relates to not make surface property to reduce, heat sealability, mechanical property, plasticity and the superior butene-1 copolymer composition of the transparency.
In recent years, butene-1 polymer comes into one's own as soft or semi-rigid resin.
But because the peak melting point (DSC method mensuration) of butene-1 polymer is 120 ℃, thereby when making film, its heat-sealing temperature is too high, lacks practicality.
In order to reduce the heat-sealing temperature of butene-1 polymer, the someone has proposed to make the method (opening clear 61-108615 communique and 60-38414 communique with reference to the spy) of butene-1 and other alpha-olefin copolymer.
But, make heat-sealing temperature be low to moderate enough low applied temps, just must carry out copolymerization with other very a large amount of alpha-olefins.Consequently easily produce films tacky and caking, make that other character of prerequisite film becomes low in practicality.
In addition, also have will a large amount of propylene copolymers and 1-Butylene copolymer be combined together and the composition made [contrast spy open clear 61-108647 number open clear 61-118449 number (No. 655397, United States Patent (USP)) with the spy]
But, the composition of being put down in writing in these communiques, because the use level of copolymerization of propylene compound is many, the fusing point of propene polymer is dominant, thereby, will produce the problem that the heat-sealing temperature of said composition can not be reduced to enough low applied temps.
The purpose of this invention is to provide a kind of butene-1 copolymer composition that makes heat-sealing temperature reduce to sufficient practical level.More specifically, the purpose of this invention is to provide a kind of surface property step-down that do not make, heat sealability, surface property, physical strength, plasticity and the good butene-1 copolymer composition of the transparency.
It is heavy that the said composition that is characterised in that butene-1 copolymer composition of the present invention contains 75～99.5%() 1-Butylene copolymer and 25～0.5%(heavy) propylene copolymer, this 1-Butylene copolymer is to be formed by butene-1 and the alpha-olefin copolymer that contains 2～3 carbon atoms, its alpha-olefin unit amount is 1～35%(mole), limiting viscosity is in the scope of 0.9～7.2dl/g, the ratio of weight-average molecular weight and number-average molecular weight is 4～15, and it is heavy to contain 1～45%(in this multipolymer) dissolve in the component of boiling diethyl ether.
It is 2～3 alpha-olefin unit that 1-Butylene copolymer of the present invention contains butene-1 unit and carbonatoms.
The example of described alpha-olefin such as ethylene unit and propylene units.
Alpha-olefin in the 1-Butylene copolymer can contain any in above-mentioned ethene and the propylene, also can contain these two kinds of unit simultaneously.Best alpha-olefin unit is a propylene units.
In this 1-Butylene copolymer, the unitary ratio of alpha-olefin unit, particularly propylene unit and butene-1 is usually 1: 99～35: in the scope 65(mole).If in the multipolymer alpha-olefin particularly the mol ratio that contains of propylene units be lower than 1, then when butene-1 copolymer composition was made film, the reduction of its heat-sealing temperature was just insufficient.On the other hand, if this ratio greater than 35, then when butene-1 copolymer composition is made into film, can be clamminess in the surface of this film, thereby make the film surface characteristic degradation.
Particularly in the present invention, above-mentioned mol ratio be preferably in 3: 97～30: 70 scope in.If this mol ratio is in this scope, the gained butene-1 copolymer composition just can produce the formed film that uniformity is better, transparency is higher.
The limiting viscosity that 1-Butylene copolymer of the present invention is measured in 135 ℃ naphthane (η) is 0.9～7.2dl/g.This limiting viscosity mainly is influential to the plasticity of butene-1 copolymer composition and physical strength.
If this limiting viscosity η is lower than 0.9dl/g, then when this butene-1 copolymer composition is made into film, the mechanical property of this film, particularly shock-resistance step-down.On the other hand, as be higher than 7.2dl/g, then the plasticity step-down.Particularly in the present invention, if limiting viscosity η in the scope of 1.0～4.0dl/g, then the mechanical property of butene-1 copolymer composition becomes very good, has also just improved simultaneously film shaped property.
The molecular weight distribution of 1-Butylene copolymer of the present invention, promptly the ratio (Mw/Mn) of weight-average molecular weight (Mw) and number-average molecular weight (Mn) is in 4～15 scope.
This molecular weight distribution makes the molding that obtains have the transparency, and is also influential to the plasticity and the physical strength of molding simultaneously.
With the 1-Butylene copolymer of prior art method manufacturing, because the distribution of its molecular weight is narrow, thus be difficult to make molding with enough plasticities, and when making film, the transparency of film is usually not enough.
Just, if the molecular weight distribution less than 4 of 1-Butylene copolymer, the then film shaped property deficiency of 1-Butylene copolymer, and the transparency variation of the film that is shaped.On the other hand, if aforesaid molecular weight distribution is wideer than 15, the transparent step-down of the film of making by butene-1 copolymer composition then.
Particularly in the present invention, molecular weight distribution is preferably in 4～10 the scope.Butene-1 copolymer composition in a little scopes not only has good plasticity, and the mechanical property and the transparency of the film that makes when being shaped of this butene-1 copolymer composition are all good especially.
The components contents that dissolves in boiling diethyl ether in 1-Butylene copolymer of the present invention is in 3～45% scopes.
Red in general, the solvability in boiling diethyl ether is low more, and then the polymerization degree of 1-Butylene copolymer is high more, and solvability is low more, and crystallinity is high more.For 1-Butylene copolymer of the present invention, the polymerization degree in the 1-Butylene copolymer low composition and crystallinity are limited if the components contents that dissolves in boiling diethyl ether in above-mentioned scope, just means.
Therefore, as it is heavy less than 3%(to dissolve in the quantity of component of boiling diethyl ether), the transparency step-down of film shaped body then is on the other hand, if heavy greater than 45%(), then since the low polymerization degree composition to contain quantitative change big, thereby produce the problem that is clamminess.Particularly as will be in boiling diethyl ether the amount of soluble component to be adjusted to 4～35%(heavy) scope in, not only the transparency of molding increases, and 1-Butylene copolymer can not produce the problem of being clamminess, thus be recommend.
According to the analysis of nuclear magnetic resonance spectrum to 1-Butylene copolymer of the present invention, the unitary block of alpha-olefin (X) is preferably in the specific scope in this 1-Butylene copolymer.
For the unitary block of alpha-olefin (X), be that the C-NMR that carries out 1-Butylene copolymer earlier measures, use " Macromolecules " 15 then, 353, (1982) Ji Zai method is determined each triad, decides the block (X) of the last alpha-olefin of 1-Butylene copolymer main chain with following formula (1)

In addition, in the formula (1), O is the unitary containing ratio of alpha-olefin in the butene-1 co-polymer in front.When alpha-olefin unit was propylene, O was the containing ratio P of propylene units.P represents with following formula usually.
P(mole %)=(Ipp+Ipb/2)/(Ipp+Ipb+Ibb) * 100
In above-mentioned formula, Ipp represents the peak strength of the propylene chain-ordering of Ipppp+Ipppb+Ibppb.Ipb represents the peak strength of propene-1-butene-1 chain-ordering of Ibpbp+Ibpbb+Ippbb+Ippbp.So Ibb represents the peak strength of the butene-1 chain-ordering of Ibbbb+Ipbbb+Ipbbp.
When 1-Butylene copolymer of the present invention was the multipolymer of butene-1 and propylene, the block of the propylene units in the 1-Butylene copolymer (X) should be below 0.01.If the block of propylene units (X) is lower than 0.001, the heat-sealing temperature of the film of 1-Butylene copolymer system step-down greatly then.
In addition, if when 1-Butylene copolymer is the multipolymer of ethene and butene-1, the I of aforementioned formula (1) is the chain block polymerization amount of ethylene unit in the 1-Butylene copolymer.The poly-amount of the chain block of this ethylene unit is represented with following formula usually:
I(mole %)=(Ieee)/(Ibbe+Iebe+Ibeb) * 100
Being used for determining the O of the block (X) of alpha-olefin, is the ethylene unit containing ratio E in the 1-Butylene copolymer under alpha-olefin is the situation of ethene.E represents with following formula usually
E(mole %)=(Ieee/2+Iebe+Ieeb)/(Ibbb+Ibbe+Ibeb+Ieee/2+Iebe+Ieeb) * 100
In above-mentioned formula, for example, Ieee represents the mole number of ethylene unit-ethylene unit in the 1-Butylene copolymer-ethylene unit chain, and is same, and Ibbe, Iebe and Ibeb represent that three kinds of monomeric units combine formed combination variety.
The block of the ethylene unit in the 1-Butylene copolymer of the present invention (X) is preferably in below 0.015.And this value is low more good more, and therefore, this value is preferably 0.If the block of ethylene unit (X) is lower than 0.015, then the heat-sealing temperature of 1-Butylene copolymer film can descend significantly.
